The film is offset-printed in four colors to resemble a piece of colorful historic Korean fabric. It's formed into a flexible cone that is dropped over a polypropylene base cone which is vacuum-metallized in gold. For protection a clear styrene acrylonitrile sleeve slides over the base cone trapping the film in between. The SAN sleeve is locked into place by the gold vacuum-metallized PP sphere that tops the closure. According to a spokesperson from LIR-USA (Yaphank NY) whose sister company LIR-France supplied the closure one of the chief challenges was to form the PET film into a cone without distorting the printing. The company wouldn't disclose details of the forming process.
